How the Oncor delivery charge works
Your bill has two parts. The energy charge is what your provider sets and competes on. The delivery charge belongs to Oncor Electric Delivery: a fixed monthly customer and metering charge plus a per-kWh delivery rate approved by the PUCT. Every provider in Denison pays the same delivery charges, which is why comparing the all-in average price on the EFL is the fair way to shop. Low-usage homes feel the fixed monthly piece more, so check prices at 500 kWh if you live in a small apartment.
